| Abstract | A system and method are provided for controlling a locomotive such that the braking effort is maintained at its optimal maximum level throughout the extended range. The method comprises detecting a first reduction in speed of the locomotive; energizing at least one solid state device connected across one or more grid resistors for a first predetermined amount of time to divert current away from the one or more grid resistors for the first predetermined amount of time; and de-energizing the solid state device after the first predetermined amount of time. The solid state device may be an Isolated Gate Bipolar Transistor (IGBT) and a plurality of solid state devices are energized, each solid state device being connected across a corresponding resistor grid. |
